If you mean where it says the name with the ammo, shells, et cetera, don't change the localization. Look for a file called hud_ammo_ppsh.urc (or something similar, that's how it would be in MOHAA and I don't make mods for Spearhead), and near the bottom, it'll say itemstate 1 or something. Delete that line, put and put this where that was:

Title "Name"

Where Name is the name you want to use. Then save that file in mohaa/mainta/ui as hud_ammo_ppsh.urc (or whatever the filename is).

Sorry, I don't know what pak file it's in, so just open up one pak file at a time, sort by type, and look for .urc files. There aren't too many paks in Spearhead, so it should take two minutes, tops.
